NCT ID NCT07389369
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 120 university students to see if their smartwatch step counts matched what they reported on a physical activity questionnaire. Participants wore an Apple Watch and filled out a short survey about their weekly activity. The goal was to understand if objective data from a smartwatch agrees with subjective self-reports.
